Military standards for use in development and production of fuzes have been prepared by the Joint Army, Navy, and Air Force (JANAF) Fuze Committee. Those field and laboratory tests which are used frequently and are applicable to a specific type of fuze or to several types of fuzes have been published so that the tests may be conducted in the same manner regardless of where the work is performed. Test laboratories using the standard tests have produced data which can be interpreted by all other fuze laboratories; therefore, the repetition of similar tests has been reduced when a fuze developed by one service is adopted by another. Special tests for unusual fuzes or components are still necessary.
